As the core of the car, the engine has always been an important reference index for consumers to buy a car, and each technical iteration of the engine not only brings a better power & fuel consumption balance, but also can further meet the more stringent emission indicators in different regions, so it is regarded by manufacturers as the core competitiveness of new products. In the domestic market, many blockbuster new cars of major brands this year will also usher in a new powertrain, and various new technology applications have also pointed out the direction for the development of the future internal combustion engine.
●Nissan HR13DDT 1.3T
▲ Service model: A new generation of Qashqai
Compared with the other two in the "two fields and one production", Dongfeng Nissan's progress in the field of small-displacement turbocharged engines is relatively slow, and it is not until the Nissan-Renault-Daimler partnership is confirmed (the cooperation is currently bankrupt) that there is really something new that can be put to hand. This HR13DDT 1.3T is essentially a product developed by Renault and Mercedes-Benz, and has little to do with Nissan. The domestic Mercedes-Benz A-Class (on sale) and the Renault Correbin (discontinued) have all been used, and the new generation of Nissan Qashqai will also eliminate the 2.0L self-priming engine in service and use this 1.3T in-line four-cylinder turbocharged engine instead.
From the perspective of the European version, the new Qashqa fuel version is equipped with a 1.3T gasoline engine with a 12V light mixing system, with 140 horsepower / 157 horsepower two tunings, and mercedes-Benz M282 1.3T engine not only has the same displacement, the difference between high and low power adjustment is not very large. At the technical level, the most typical feature of this engine is the triangular cylinder head design, the structure is very compact, which is conducive to reducing the mechanical loss of lubrication /cooling/gas distribution and other systems, while the quality of the whole machine/ center of gravity is also lower, which can reduce costs and improve efficiency; the cylinder body part, the model also adopts a cylinder liner design, relying on the special coating of the cylinder wall to achieve friction reduction, weight reduction, and good heat dissipation.
Of course, because of the design of the triangular cylinder head, this engine uses a more traditional 2/3 cylinder exhaust outlet combined exhaust manifold design, compared to the more mainstream cylinder head integrated exhaust, this traditional practice will have a lower utilization rate of exhaust heat, such as the warming speed will be slower, thermal management may be almost interesting. In addition to this, this engine has a variable cylinder on the Mercedes-Benz A-class (turning off the 2/3 cylinder valve and injector to idle the piston), and this technology is not known to be reflected in the new generation of Qashqai.
It is worth mentioning that the new Qashqai also has an e-power extender hybrid version in the European market (does not support external power charging), and its technical route is the same as that of the domestic Xuanyi e-power, which relies on the motor to drive the wheels, and the engine only acts as a range extender to charge the motor/battery. The difference is that the new Qashqa European version of the range extender is a 1.5T in-line three-cylinder engine, which can be understood as a special version of the extended range of the new Qijun VC-Turbo 1.5T engine, with poor power data, but the economy is better after electrification.
Honda 1.5L i-MMD
▲Service models: XR-V Sharp Hybrid, etc
Honda Automobile has always regarded the powertrain as the core competitiveness of the brand, so there is no shortage of "with T" engines of the Niu X, such as Honda's active 1.5T engine domestic/foreign reputation is very good, the data is good, the tuning is also very mature, as small as the Binzhi can be used; the K20 redhead machine equipped with the Civic TYPE R is regarded as one of the ceilings of the transverse front-drive engine.
In the HEV oil-electric hybrid market, the Honda i-MMD powertrain equipped with Accord and Xiangyu is also one of the few hard-core products that can "break the wrist" with Toyota THS, but Toyota has popularized THS (that is, the dual engine series) on all models under the TNGA architecture, while Honda has a slower pace, and the i-MMD is currently only a few cars in use.
Starting in 2022, Dongfeng Honda and GUANGC Honda have begun to fully expand the product lineup of i-MMD oil-electric hybrid, the first thing that will meet with consumers is the new generation of XR-V models that will be listed in August, and then The Civic, Model, Binzhi and other models will also launch oil-electric hybrid versions. In addition, the new generation of CR-V will also be officially launched within this year, with a high probability that fuel, HEV, AND PHEV will appear simultaneously, and it is even possible to derive an electric four-wheel drive version.
From the perspective of the European market, the new generation of HR-V (XR-V/Binzhi) uses a 1.5L engine-based oil-electric hybrid, that is, the one on the Hemisphere Sharp Hybrid, while the Civic e:HEV uses the 2.0L engine-based oil-electric hybrid, that is, the One on the Accord Sharp Hybrid. It is unclear how the future domestic version will be decided.
Honda i-MMD
Toyota THS
As a Representative Of Japanese Hybrid, Honda i-MMD will inevitably be compared with Toyota THS, although both are dual motor electromechanical coupling modules, but the two still have certain differences in structure, Honda's dual motors use coaxial structure, its coupling with the engine mainly relies on gear sets / clutches, can be more thoroughly decoupled, in order to ensure stable low fuel consumption at the same time, pure electric mode also has a better power performance, can be better compatible with green card plug mix. Toyota's dual motor is a dual-shaft structure, and the coupling with the engine relies on the planetary gear set, although the speed / torque balance, power shunting will be more efficient, but the speed and speed can not be completely decoupled (the plug-in hybrid version only adds a one-way clutch), and the low-power motor in pure electric mode is obviously not able to support the normal driving of the vehicle, and the power recovered by the braking energy will be limited. Simply put, the blue card hybrid is not black, and the green card hybrid is more crotch-pulling.
●Volkswagen EA211 1.5TSI evo2
▲Service model: FAW-Volkswagen Sagittarius
According to the declaration information, FAW-Volkswagen will launch a new Sagitar 300TSI model, the biggest change of the car compared to the active model is to replace the second generation of EA211 engine, not only the displacement increased by 1.5L from 1.4L, but also more technical applications have also made its fuel economy compared with the active EA211 series also comprehensively improved.
In terms of data, the maximum power of the domestic EA211 1.5TSI evo2 is 118kW, and the maximum torque is 250 Nm (it is also possible to be 260 Nm), which is slightly higher than the active 1.4TSI engine (110 kW), but the difference is not too big. The same is the 1.5T engine, the blue whale 1.5T, the moment wave 1.5T, Kunpeng 1.6T launched by major independent car companies will be much more "expanded", and the Mercedes-Benz M254, Nissan VC-TURBO, and GM's eighth-generation Ecotec data of the joint venture car companies have also generally reached 200 horsepower / 300 Nm of book data.
Technically, the second generation EA211 compared to the first generation to join the Miller cycle, 350Bar direct injection, VGT turbine and other advanced technologies have been applied, the first two in the active service of the third generation EA888 has been applied, but VGT variable section turbocharger, this thing is indeed the first appearance, compared to the traditional exhaust gas turbine its biggest advantage is to better balance the response speed and explosive force of the intake pressure. In addition, from the overseas version of the Golf MK8, the second generation EA211 is also compatible with the 48V mix system, at present, Sagitar 300TSI does not seem to inherit this electrification technology.
●Volkswagen EA888 2.0TSI evo4
▲Service model: SAIC Audi Q6
Like EA211, volkswagen EA888 engine also ushered in an iterative version this year, which is the fourth generation of EA888 2.0TSI evo4 model, the first time in China to modify the Porsche Macan in the middle of the year, and the real application in the joint venture car is SAIC Audi's first medium and large SUV - Q6, the car has already had declaration information, is expected to officially meet with the majority of consumers this year.
The EA888 engine is a magic machine of Volkswagen, the classic cast iron cylinder block gives the model a strong modification potential, the domestic third generation of the minimum power is only 150Ps (110kW) (Audi A4L minimum, has been discontinued), and on the Golf R, its book data reached 235kW/ 420Nm (EA888 2.0TSI EVO4 IK3), which is stronger than many V6 engines. As for the Audi Q6, the declaration information shows that its maximum power is 265Ps (195 kW), which is also far higher than the active third-generation EA888.
Audi Q6 is a joint venture car, but the current fourth generation EA888 has not been localized, this engine is the whole machine imported and then loaded, so technically, what Miller cycle, 350Bar direct injection have applications, the exhaust side of the variable valve lift will not be absent. Looking at the powertrain, SAIC Audi's seven-seat medium and large SUV is even more "fragrant" than the imported Q7, unfortunately, this is an MQB horizontal platform car, rather than the A4, A6, Q5 and other models of MLB vertical platform.
Volkswagen/Audi: Triple-clutch P2 hybrid layout
Judging from the real car shown in the declaration map, this car looks basically the Audi version of Tu Ang, which has changed the iterative engine. With the current electrification progress of Volkswagen's internal combustion engine, it is likely that it will not be able to keep up with the rhythm of Toyota THS, Honda i-MMD, BYD DM-i, Chery DHT, and the north and south volkswagens seem to have little interest in green card plug mixing, after all, the German single motor hybrid has seriously lacked competitiveness in the face of Japanese/Chinese dual motor hybridization, and the ID series pure electric vehicle is the life-saving straw for Volkswagen to face the double integration policy.
● Mercedes Benz M254 2.0T
▲ Service model: Beijing Benz C 350 eL, a new generation GLC
The new generation of C-class for the first time using Mercedes-Benz's latest development of M254 1.5T engine, although the displacement is compared to the Audi A4L, BMW 3 series, but the 204 hp / 300 Nm book data is indeed the ceiling of this displacement, plus is the ISG motor-based 48V mix system, in fact, the power response of the car is completely without fear of any pure fuel vehicle equipped with a 2.0T engine, and even has a certain advantage in economy.
Of course, the author is not to Beijing Mercedes-Benz washing floor, personally always think that the luxury car must have the appearance of a luxury car, the European version of the C-class gasoline version of the entire series is M254 2.0T with light mix, with what domestic production after shrinking, the money saved by the displacement tax is not reflected in the price of the car, what reason do users have to pay for it.
Judging from the latest phase of the Ministry of Industry and Information Technology declaration information, the domestic Mercedes-Benz C-class will launch a C 350 eL version, which is a plug-in hybrid vehicle with A P2 layout, and the engine part is the M254 2.0T engine (150kW), with a drive motor with greater power than the light hybrid version, its performance will undoubtedly be a lot ahead of the current C-class, and it is even possible to break 100 within 6 seconds.
The new generation of Mercedes-Benz GRC
In addition, the new generation of Mercedes-Benz GLC has also been exposed many times in the real car spy photos, is expected to be the first in the near future world premiere, as a C-class SUV version, the car will most likely be equipped with no crankshaft pulley train M254 series engine. As for the future domestic version, maybe Beijing Benz will also produce a 1.5T "China Special Edition", who knows...
